Following Cook's first book, Fat of the Land, The Mushroom Hunters is an unprecedented look into the undercover world of wild mushrom foraging, marketing and selling. It's a business of anonymous pickers, sometimes shady middlemen, and a largely misunderstood marketplace for consumers. Lang embedded with foragers from all over the country, from Alaska to Colorado, California through Oregon and of course into our deep woods here in Washington to dig into this subculture. The book is an adventure, an investigation and a great yarn that, at times, reads like a mystery.
